From Wikipedia:
http://en.wikipedia.org/wiki/Why_the_...
why the lucky stiff (often known simply as why, _why) was an anonymous, but prolific writer, cartoonist, musician, artist, and computer programmer notable for his work with the Ruby programming language. Along with Yukihiro Matsumoto and David Heinemeier Hansson, he was seen as a key figure in the Ruby community.
His best known work is Why's (poignant) Guide to Ruby, which "teaches Ruby with stories." Paul Adams of Webmonkey describes its eclectic style as resembling a "collaboration between Stan Lem and Ed Lear". Chapter three was published in The Best Software Writing I: Selected and Introduced by Joel Spolsky.
On 19 August 2009, his online presence was drastically truncated; his accounts on Twitter and GitHub were shut down, along with many of his personally maintained sites.
In April 2013, a complete book attributed to _why was digitally released via the website whytheluckystiff.net and the GitHub repository cwales. It was presented as individual files of PCL (Printer Command Language) without any instruction on how to assemble the print outs into a book. Based on timestamps from the git repository, Steve Klabnik compiled the pages in the order in which they were released into a PDF file which he titled CLOSURE since the book provides some resolution to the story of _why. Although no authorship is claimed in either the book or the git repository, the writing style and content are remarkably comparable to that of _why.
